The bimetallic cobalt-iron MOF (CoFe-MOF) shows significant promise as an electrocatalyst for water splitting, addressing limitations of traditional metal-organic frameworks (MOFs) like poor conductivity and stability. Electrochemical tests indicate a low overpotential of 106 mV for the hydrogen evolution reaction (HER) and 202 mV for the oxygen evolution reaction (OER) at 10 mA cm⁻². An electrolyzer utilizing CoFe-MOF functions effectively as both anode and cathode, achieving a total water splitting cell voltage of 1.42 V at the same current density, marking it as a viable option for green hydrogen production.
